HALLECK FLOYD, OF DUBLIN, INDIANA.

SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent N o. 680,140, d'ated August 6, 1901.

Application filed April 4:, 1901.

To all whom, t may concern:

Be it known that I, HALLECK FLOYD, a citizen of the United States, residing at Dublin, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Spark-Arresters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a spark-arrester for steam-railway trains.

The object of the invention is to provide a spark-arrester which shall be simple of construction, durable in use, and which may be readily and with little expense attached to the ordinary railway-train now in use and by means of which the products of combustion escaping through the smoke-stack of the locomotive will be discharged from the rear end of the train, thus removing many objectionable features incident to travel, as well as lessening the liability of damage due to condagration caused by the live sparks.

With this object in view the invention consists in certain features of construction and combination of parts, which will be hereinafter fully set set forth.

In the accompanying drawings, Figure l is a side elevation of a portion of a railwaytrain, illustrating the application of my invention; and Fig. 2 isa longitudinal sectional view through the engine smoke-stack and the hood connected thereto.

Referring to said drawings, l denotes a series of pipesections,the forward ends of which are funnel-shaped, to take the straight rear ends of the contiguous pipe-sections. These pipes are connected to the cars, as indicated,

and extend the whole length of the train. The front section of pipe is provided with an enlarged funnelshaped. hood 3, having a lower opening with asurrounding edge band a, through which passes the smoke-stack 4 of the engine, the band also serving the purpose of preventing cinders from passing ,between the stack and the connecting edge of the opening. The upper portion of the funnel-shaped hood is provided with an enlarged opening arranged above the lower opening. A door 5 is hinged to the hood for operating the upper opening by means of an arm 6,- seserin No. 54,321. (No model.)

cured to said door, having a cord or wire 7 leading to the cab of the engine. When the train is not in motion, this door is open, so that the draft may be direct through the smoke-stack and the hood out through the hood-opening.

The forward open end of the hood is provided with an apron which extends from the upper side of the hood and covers from onethird to one-half of the opening in said hood. The apron is inclined from its top slightly rearward, for a purpose hereinafter described. When the train is in motion, the air will be drawn through the open end of the hood and will conveyl the products of combustion escaping from the smoke-stack to the'rear end of the train, and when they have reached this point the live sparks become extinguished, and when discharged from the rear end of the rear pipe-section they are perfectly harmless and will not set anything on iire with which they may come in contact. As the sparks are discharged through the smokestack into the hood,the tendency of the sparks is to be drawn rearward through the pipe-sections, yet a large number would, in the absence of the apron, be guided out of the hood by its inclined wall, thus evading the object of the invention. By the provision of the apron the sparks discharged from the smokestack strike the upper surface of the hood, and those that would otherwise escape through the front end of the hood will strike the apron and drop into the draft and be carried back through the pipe-sections. .By inclining the apron slightly the force of the air within the area circumscribed by the periphery of the hood will be concentrated, thus creating an increased draft and reducing to a minimum the liability of any of the sparks escaping through the front end of the hood.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood Without requiring an extended explanation.

The deviceis extremely useful for the purpose for which it is designed and maybe placed upon the market at a comparatively small cost.

Various changes in the form, proportion, and the minor details of construction maybe IOO with a hinged door, and means connected therewith for opening andl closing the same, g an inwardly-inclined apronsecured to the upper surrounding edge portion of the funnel and also to the body portion thereof, the lower Openingaprovid'ed with a band surrounding its edge portion, whereby the smoke-stack of the engineis mounted therein tohave direct communication with the said upper Opening, the said edge band serving to prevent einders from passing through the Opening, substanti'ally' as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- DGSSGS.

HALLEOK FLOYD.
